US stocks & ETFs · email alerts · free to start
Stop finding out after the move.
No app to open. No charts to babysit. Set a price target, a % swing, or an earnings date once — Computo watches the US market and emails you the moment it hits.

NVDA crossed your price target
You asked to know when NVDA hit $140. It did.
Illustrative example
Built to be quiet and exact.
Alerts you can trust to fire once, on time, and never spam you.
Cooldowns, not noise
One alert per trigger, then a cooldown. A stock hovering at your target won't flood your inbox — you get the signal, not 50 emails.
Market-hours & date aware
Prices checked against US market hours, timestamps in ET. Earnings and ex-dividend alerts fire a few days ahead — never after the cut-off.
